複数全角スペースを1個に置き換えて 改行を全角スペース２こに変換して表示

<?php $ryoukin = preg_replace("/[　]+/u","　",get_post_meta($post->ID,料金,true)); 
 $ryoukin =str_replace("\r\n", '　　', $ryoukin);
 echo $ryoukin;?>

05naviの記事件数　登録　何件？

ファンクションへ
オリジナル関数だと思う

//特定のカテゴリと特定のタグで絞った記事数の表示方法
function taxonomy_found_posts_num() {
    $args = array(
'post_type' => array('shoku','asobu','share','seikatsu','iryou','manabu','koukyou','ofuroyado'), //カスタム投稿名
    );
    $my_query = new WP_Query($args);
    return $my_query->found_posts;
}

//表示箇所に
//<?php echo taxonomy_found_posts_num('hokkaido','タグ１'); 件<br />
//<?php echo taxonomy_found_posts_num('aomori','タグ２'); 件

上記正式コード

<?php
function taxonomy_found_posts_num($cat_slug,$tag_slug) {
    $args = array(
        'post_type' =>'post',
        'tax_query' => array(
            'relation' => 'AND',
            array(
                'taxonomy' => 'category',
                'field' => 'slug',
                'terms' => $cat_slug,
            ),
            array(
                'taxonomy' => 'post_tag',
                'field' => 'slug',
                'terms' => $tag_slug,
            ),
        ),
        'posts_per_page' => 1
    );
    $my_query = new WP_Query($args);
    return $my_query->found_posts;
}
?>

    <?php 

//特定のポストタイプと特定のユーザーIDで絞った記事数の表示方法
function taxonomy_found_posts_num1($post_type,$user_id) {
    $args = array(
'post_type' => $post_type, //カスタム投稿名
'author' => $user_id,
    );
    $my_query = new WP_Query($args);
    return $my_query->found_posts;
}

//ログインユーザーのIDを取得
$user = wp_get_current_user();
$user_idd = $user->get('ID')."\n"; // ID

//出力

アロー演算子

codeigniterでDBアクセス時に用いるもの

http://codeigniter.jp/user_guide_ja/database/examples.html

$query = $this->db->query('SELECT name, title, email FROM my_table');

foreach ($query->result() as $row)
{
    echo $row->title;
    echo $row->name;
    echo $row->email;
}

echo 'Total Results: ' . $query->num_rows();
